Since my acne journey started 11 years ago I've crossed paths with any and every medication combination you can imagine (except Accutane). I've tried adapalene, isotretinoin gel, tretinoin, tazarotene, benzoyl peroxide, clindamycin, azelaic acid, and the list goes on, and on, and on. I had not however tried Retinaldehyde. I had given up on my retinoid journey because I was always left scarred and worse than before.
